Could you please have try with the latest mainline kernel: https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.3/
If that kernel doesn't work, let us have a try with replacing the current graphic driver amdgpu to the amdgpu-pro. I will update a new comment to explain how to install amdgpu-pro if the kernel v5.3 is confirmed to not work. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1834771 Title: No HDMI-audio after kernel 4.15.-0.50 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1834771/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
